I’m using MX Linux AHS, it is Debian based, it is always up to date, like latest firefox a few hours after it’s out, kernel 6.12.17 as of today, etc.
It has no systemd, no snap, no flatpak. It just uses the good old .deb and everything is working fine.
I still have my old HP Mini311 netbook, AntiX or Linux MX 32bits works well on it.
